Multi-layer ceramic capacitor and method of producing the same

Abstract

A multi-layer ceramic capacitor according to an embodiment of the present invention includes a multi-layer, side margins and offset sections. The multi-layer includes internal electrodes and dielectric layers alternately laminated. The side margins are configured of a dielectric and disposed to cover side faces of the multi-layer. The offset sections are made with amorphous areas or gap areas. The offset sections are formed between the internal electrodes and the side margins such that ends at side faces of the internal electrodes are offset from the side faces to an inward direction of the multi-layer.

What is claimed is: 
     
       1. A multi-layer ceramic capacitor, comprising:
 a multi-layer where internal electrodes and dielectric layers are alternately laminated in a first direction; 
 side margins comprising a ceramic material and disposed to cover side faces of the multi-layer from a second direction orthogonal to the first direction; and 
 offset sections formed between the internal electrodes and the side margins such that ends at side faces of the internal electrodes are spaced apart from the side faces to an inward direction of the multi-layer and made with amorphous areas or gap areas, the amorphous areas constituted of a vitreous material, the gap areas made with air gaps, the offset sections respectively formed in the ends of all of the internal electrodes including an uppermost internal electrode and a lowermost internal electrode in a cross section viewed from a third direction orthogonal to the first direction and the second direction, 
 wherein the amorphous areas or gap areas are in direct contact with the ends of all of the internal electrodes, respectively, and 
 wherein the dielectric layers of the multi-layer are disposed between the offset sections adjacent to each other in the first direction. 
 
     
     
       2. The multi-layer ceramic capacitor according to  claim 1 , wherein
 a width of each offset section is 0.1 μm or more.
